Why Black Hole Interiors Grow (Almost) Forever (quantamagazine.org)

I wonder what definition of "volume" Susskind is using here? Something coordinate independent, presumably, though I don't really see how it's possible to get around the issue of GR allowing many equally valid slices of spacetime to be called "the present moment". Also, they can't be referring to the Schwarzschild metric here, since that's static, and the article states that the volume is increasing over time. It has to be some more complicated solution that describes the collapse of a star into a black hole. Maybe the Schwarzschild metric is the end state of such a collapse process and has infinite volume according to Susskind's definition, though that's just baseless speculation.
